Abstract Current changes of the environment represent the major threats to the sustainable development and are one of the biggest problems, with negative consequences on the national economy. The accelerated pace of these changes is shareholder and by the manifestation of extreme events, which in recent years become more intense and frequent. The drought events frequent manifestation over the Republic of Moldova territory, in the context of climate change, requires a scientific monitoring adjusted. The dry period’s manifestation is greatly conditioned by increasing daytime temperatures (above 25°C) and the lower relative humidity (below 30%). At present, on the background of climate change, there is an increase of dry days. Over the Republic of Moldova territory, their occurrence during growth and development of crops particularly damaging role in obtaining low yields. Meanwhile, prolonged dry periods, may possibly cause fires, at the same time can determine lands’ irrigation and surface water quality. In this context, there is a need to estimate the evaporation’s spatial and temporal variability, the number of dry days and their correlation to Dry Periods Index (Izu), the index developed at regional level.

Abstract The viticulture, a traditional branch of the national economy, is closely related to climatic conditions because the Republic of Moldova territory represents the northern border of its territorial location. Therefore the knowledge of regional particularities of grapevine productivity formation in dependence of current agro-climatic conditions is of particular interest. Along with accelerated climate change in last decades over the Republic of Moldova territory, we find that are essential changes concerning agro-meteorological conditions, at the same time comprehensive researches that would reflect the actual impact of climate change on grapevine are limited. There are known researches, but in the context of changes that occur at regional level it is necessary to supplement permanently the database in order to elaborate an appropriate estimation of current climate conditions. The above reported facts show the importance of parameters influencing the grapevine productivity time and space study in Republic of Moldova.

<p>Irrigated agriculture is dependent on an adequate water supply of usable quality. The analysis of physico­chemical parameters of surface water inJember District was done for the criteria of irrigation water quality. Surface water comprises spring water, falls, rivers, and tertiary irrigation channels. For this purpose, three sectors or locations were chosen to take twenty seven water samples in the summer season (September to October, 2013). DO, electrical conductivity (ECw), pH, and water temperature values were measured directly in the field,while analyses of nitrate (NH3-N), orthophosphate, total dissolved solids (TDS), and bicarbonate (HCO3-) was conducted in a laboratory. The results indicated that ECw, TDS, pH, water temperature,NH3-N, and orthophosphate were under the limits set out by the Rules of the Republic of Indonesia Government (PP RI) No. 82, 2001, for water quality standard and FAO for irrigation water quality standard. Thus, the surface water of Jember District was considered to be suitable for irrigation at the sampled location.</p><p><br /><strong>Keywords</strong>: Surface water quality; irrigation; physico-chemical parameter; Jember District.</p>

Abstract The accelerating pace of climate change is associated to weather-climate related risks manifestations, which in recent years are becoming more intensive and more frequent. Unfortunately, we find that far at regional level there are no a basic scientific information which could highlight their specific spatio-temporal manifestation. In this context, criteria for several weather-related risks identification were quantified, the main ones being material damages, the number of casualties and victims and not the least - and the period they occur. The identified weather and climate related risks may be subject to a complex spatiotemporal analysis, having as a research tool - Geographic Information Systems.

Abstract. The design and evaluation of solutions for integrated surface water quality management requires an integrated modelling approach. Integrated models have to be comprehensive enough to cover the aspects relevant for management decisions, allowing for mapping of larger-scale processes such as climate change to the regional and local contexts. Besides this, models have to be sufficiently simple and fast to apply proper methods of uncertainty analysis, covering model structure deficits and error propagation through the chain of sub-models. Here, we present a new integrated catchment model satisfying both conditions. The conceptual iWaQa model was developed to support the integrated management of small streams. It can be used to predict traditional water quality parameters, such as nutrients and a wide set of organic micropollutants (plant and material protection products), by considering all major pollutant pathways in urban and agricultural environments. Due to its simplicity, the model allows for a full, propagative analysis of predictive uncertainty, including certain structural and input errors. The usefulness of the model is demonstrated by predicting future surface water quality in a small catchment with mixed land use in the Swiss Plateau. We consider climate change, population growth or decline, socio-economic development, and the implementation of management strategies to tackle urban and agricultural point and non-point sources of pollution. Our results indicate that input and model structure uncertainties are the most influential factors for certain water quality parameters. In these cases model uncertainty is already high for present conditions. Nevertheless, accounting for today's uncertainty makes management fairly robust to the foreseen range of potential changes in the next decades. The assessment of total predictive uncertainty allows for selecting management strategies that show small sensitivity to poorly known boundary conditions. The identification of important sources of uncertainty helps to guide future monitoring efforts and pinpoints key indicators, whose evolution should be closely followed to adapt management. The possible impact of climate change is clearly demonstrated by water quality substantially changing depending on single climate model chains. However, when all climate trajectories are combined, the human land use and management decisions have a larger influence on water quality against a time horizon of 2050 in the study.
